Can't start the Client with the mod enabled

[SirBlueAxolotl]

If I start the client, i get "Process 'command 'C:\Users\Mario\AppData\Local\Programs\Eclipse Adoptium\jdk-21.0.6.7-hotspot\bin\java.exe'' finished with non-zero exit value -1" and if i don't use the mod, minecraft starts normally

ModItems. — This is the static initializer block of your ModItems class.

Item id not set — Minecraft expects every Item to have a valid RegistryKey or ID set during initialization. You're trying to create or register an item without properly registering it with the Minecraft Registry.
